The correct order of basic strength of the following amines strictly in the gaseous phase is: — GOC and Organic Chemistry Basics Chemistry Question

💡 Solution & Explanation

In the gaseous phase, there are no solvation (hydration) effects to stabilize the conjugate acid. Basic strength relies entirely on the $+I$ effect of the alkyl groups pushing electron density onto the nitrogen atom. Thus, a tertiary amine (three $+I$ groups) is the strongest base.
